BTW, I also noticed something strange today (and I remember seeing it previously). I turned most of my settings way down in MSFS. In doing so my FPS was in the mid 50s, dipping down into the 40s occasionally. In the FPS tool my GPU was solid yellow and my CPU was almost solid green. But regardless of what I tried I was unable to get MSFS to be stutter free. Stutters were bad. I tried RivaTuner. I changed all the options in MSFS. The only way I was able to get things smooth again was....to turn the settings back up. Now i have around 25 to 32 FPS and it is very smooth. I don't get it but this might be a clue. 

It is like my GPU needed to be stressed out to stop the stutters.  

This is probably because by turning the settings down, you actually become CPU bound. Then when you start turning things up, you become GPU bound. This is why, sometimes, its actually better to run with higher settings to smooth the sim out. You take the load away from the CPU and place it on to the GPU, which seems to do a much better job at handling it. Spread the load so to speak. 

There was a better explanation that I can provide about this, somewhere on these forums.

>> I think you are right Ian. Also makes we wonder about upgrading my GPU without doing a CPU upgrade also. Might be a stutter fest.

I assume you have already  set power management to maximum performance (see below) ?  That is apparently meant to stop it idling which can cause GPU stutters .

There is always a way to increase GPU load: even if you have all the "pure GPU" settings (clouds, filtering etc.) on ultra and find you are still CPU-limited (easy to check by enabling FPS in dev mode and seeing if it ever says 'limited by main thread'), you can always increase the render scaling beyond 100%, which will add load to GPU but not CPU and should give some improvements in visual quality (albeit slight).  So, if you are thinking of upgrading your GPU now to increase your visual settings, but not upgrade your CPU until later due to some practical constraints, I wouldn't worry about stutters.  However, you may well not be able to get any improvement in FPS - or terrain LOD (which hits both CPU and GPU) - without inducing stutters, so if that's what your after then upgrade both together.

I do have it set to prefer maximum performance. Maybe i should try changing this?

Gotcha. So i can get more eye candy but probably not higher FPS.

I see, well that´s a pity then. Would it work if I get the DP cable and connect it with HDMI/DP adapter to my monitor? Don´t want to buy a new monitor.

I am not 100% sure but I guess it will not work in that way.

For Freesync monitors GSync (compatible) mode must be set in nVidia control panel.

Make sure the setting looks like the following:

Now have my DP cable and all drivers are up-to-date. I now am able to set G-sync as per your graphic.

Now will see what happens!

Thanks

What is your VRR range of your monitor? Be sure to stay within that in MSFS

@Ianrivaldosmith why do I find that?

At present my 3440x1440 native has a refresh rate of 75Hz.

What model is it? 

Samsung S34J55

Found this for you:-

you will be able to synchronize the monitor’s refresh rate with the GPU’s frame rate which will remove all screen tearing and stuttering within the variable refresh rate range of the Samsung S34J55W which amounts to 48Hz-75Hz/FPS (Frames Per Second).

So, it will only work between 48fps and 75fps. You’ll need minimum 48fps in msfs at all Time. 
This is why I always, if money allows, advise people to purchase a G-Sync hardware based monitor (preferably g-sync ultimate) . They have VRR of 1-100+

My Samsung C27HG70 (Freesync) works under 48 fps too by doubling the framerate (i.e. for 40 fps it refreshes at 80 Hz).

Do GSync HW based monitors support very low refresh rates such as 1 Hz??

G-sync works all the way down to 30fps before any doubling.

GSync is not like FreeSync, there's no "range it must adhere to", it works at any FPS rate, even at 2 FPS. The GSync module multiplies the frames if necessary to always display something in the effective range of the monitor's panel, and it does not introduce any lag. It only does this below 30fps. 

At 30FPS and above it will perfectly match the games FPS. This is why the more expensive  monitors are better, because they have no flickering at the lower FPS (30-50) (which flight sims are notorious for).
